PIANO PEDAL ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 454,713, dated June 23,1891.

Application filed March 4, 1890. Renewed April 17, 1891. Serial No.389,268. (No model.)

To all whom it may concern'.-

Be it known that I, GEORGE CARL AUG Us'r CLASS, of Philadelphia, in thecounty of Phila delphia and State of Pennsylvania, have invented a newand Improved Piano Pedal Attachment, of which the following' is a full,clear, and exact description.

The invention relates to piano or organ pedal attachments such as shownand described in the Letters Patent No. 186,110, granted to me January9, 187 7.

The object of the invention is to provide a new and improved pianopedalattachment which is simple and durable in construction, and speciallydesigned to enable persons of small stature to conveniently rest theirfeet While performing on the piano and also to actuate the pedals.

The invention consists of certain parts and details and combinations ofthe same, as will be hereinafter fully described, and then pointed outin the claims.

Reference is to be had to the accompanying' drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front view of the improvement. Fig. 2 is a side elevationof the same as applied, part ofthe piano being .in section. Fig. 8 is asectional plan view of the same on the line .fr :c of Fig. 2, and Fig.4t is a sectional plan view of the same on the line y i/ of Fig. 2.

The improved pedal attachment A is provided with a suitably'constructedbase D, adapted to rest on the floor next to the piano, directly underits pedals. On the base B, near its front, is formed anupwardly-extending lug O, in which is secured the hollow post D, inwhich is iitted to slide vertically the rod E, adapted to be secured inany desired position in the post D by a set-screw F. On the upper end ofthe rod E is pivoted the platform or footerest G, on the under side ofwhich are pivoted the two V-shaped foot-arms 1I H', adapted to extend attheir free ends over and in the rear of the platform G, so as to bewithin convenient reach of the performers foot. The two foot-arins Iland H are preferably located on the sides of the platform and extendrearward and upward, as is plainly shown in Figs. 1 and 2.

The free ends of the foot-arms H and Il are pivotally connected with thedownwardly-cxtending tubes l and l', respectively, in the lower end ofwhich are Iitted to slide the rods J and J", respectively, adapted to besecured in any desired position in the said tubes I and I by set-screwsl. The lower ends of the rods .l and J are pivotally connected with thepedal-arms L and L', respectively, provided with rubbercushionsN and N',respectively, adapted to rest on the tops of the pedals O and O',respectively, of the piano l), on which the attachment is to be used.

The rods J and J, held to telescope in the tubes I and l', form with thelatter links which connect the footarms ll and Il', rcspectively, withthe pedal-arms L and L', respectively. rllhe pedal-arms L and L arepivoted on ascrew-rod Q, screwing in a sleeve R and adapted to securethe said sleeve to the post D, on which the sleeve is held to slide.

On the lug C is held a transversely-extending plate S, having' a centralaperture through which passes the post D, the inner end of the saidplate S being provided with upwardlyextending teeth or lugs S', ada-ptcdto engage the under side of the bottoni of the piano on which the deviceis used. (See Fig'. 2. Through the front end of the plate S, passesloosely a bolt T, secured in the' base B and on which screws a nut U,pressing against the top of the plate S and serving to securely hold thedevice in place on the piano.

The operation is as follows: rlhe device is applied by setting' the baseD under the pedals O and O of the piano l in such a manner that the postD passes between two pedals and the plate S engages with its projectionsS the bottom of the piano P, as is shown in Fig. 2. rlhe operator thenscrews the nut U downward so as to exert a pressure on the front end ofthe plate S, to securely press the lugs or projections S into thebottoni of the piano. By this means the device is securely clamped inplace on the iioor and to the piano P. The operator next loosens theset-screw F and raises or lowers the rod E to such a height that theplatform G forms a convenient rest for the feet of the performersit-ting in front of the piano. The performer then carefully loosens thesetscrew Q, and raises or lowers the sleeve R, so that the foot-arms IIand II are in their uppermost position--that is, project above they rearof the platform G, as illustrated in Figs. l and 2. At the same time thepedal-arms L and L extend in about a horizontal position and rest withtheir cushions N and N on top of the pedal O and O. In order to makethis adjustment complete, the rods J and J slide in the tubes I and Iuntil the proper position is reached, as above described. The severalset-screws are then fastened up. New when the performer does not use thepedal he simply rests his feet on the platform G, and when he desires touse either of the pedals, he presses with his respective foot on thefoot-arm II or I-I, thus imparting a downward movement to the linkcomposed of the tube I and the rod J, or the tube I and the rod J', sothat the said links `impart a downward swinging motion to the respectivepedal-arm L or L which presses the respective pedal O or O. Then theperformer releases the pressure on the respective foot-arm H or II', theusual pedal-spring,` returns the pedal, and the several parts rest on itto their former position.

It will be seen that this device can be readily applied to a piano andcan be adjusted to any desired height, so as to accommodate persons ofdifferent statures. At the same time the device forms a footmrest forthe performer to rest his feet on while not using the pedals.

Ila-ving thus fully described my invention, I claim as new and desire tosecure by Letters Patent1 l. The combination, with the base having,` apost or standard provided at its upper end with a foot-rest, of twofoot-arms pivoted at their outer ends to the under side of the said restand projected upwardly at their inner ends above the said rest, linksdepending` from said inner ends, and oppositely-projecting pedal-armspivoted at their inner ends to said post and pivoted at their outer endsto the lower ends of the links, substantially as set forth.

2. In a piano pedal attachment, the combination,with abase and a lugformed thereon, of a plate resting` on top of the said lug,` and adaptedto engage at its inner end the botn tom of the piano, a screw-rodsecured on the said base, andra nut screwing on the said screw-rodagainst the said plate, substantially as shown and described.

3. In a piano pedal attachment, the conibtnation, with a post, of asleeve held adjustably thereon, pedal-arms pivotally connected with thesaid sleeve and adapted to rest on the pedals, extension-links pivotallyconnected with the said pedal-arms, foot-arms pivotally connected withthe said links, and a platform or foot-rest held vertically adjustableon the said post and on which the said footarms are pivoted,substai'itially as shown and described.
